512/500 F Bearing Product Overview & Core Advantages
The 512/500 F is a metric thrust ball bearing engineered for applications demanding exceptional axial load capacity and robust construction. Its design is optimized to accommodate heavy thrust loads in a single direction, making it a critical component for high-stress industrial environments. Manufactured from high-grade 52100 Chrome Steel for both rings and balls, this bearing ensures superior durability and consistent performance under demanding operational conditions.
512/500 F Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Technical Meaning |
|---|---|
| 512 | Indicates a thrust ball bearing series with a flat seating surface on the shaft washer. |
| 500 | Specifies the bore diameter of 500 mm. |
| F | Signifies a machined brass cage or a pressed steel cage, providing stability and strength for the rolling elements. In this specific bearing, the cage material is Stainless Steel. |
512/500 F Bearing Structural Features & Performance Benefits
- High Axial Load Capacity: Engineered with a large contact angle and robust construction, this bearing delivers an exceptional axial static load rating of 1,530,000 lbf and a dynamic load rating of 227,250 lbf, making it ideal for applications with significant unidirectional thrust forces.
- Precision Ground Components: The rings and balls are precision-ground from 52100 Chrome Steel, ensuring smooth operation, reduced friction, and extended service life.
- Durable Cage Design: The stainless steel cage reliably separates and guides the balls, maintaining optimal alignment and performance, even under high-stress conditions.
- Open Seal Design: The open configuration allows for easy re-lubrication and is suitable for applications where external sealing is provided by the adjacent machine structure.
- Strict Dimensional Tolerances: Features tight dimensional tolerances on the bore diameter, outside diameter, and width, ensuring precise fit and reliable performance in the assembly.
512/500 F Bearing Typical Application Areas
This high-capacity thrust ball bearing is ideally suited for heavy-duty machinery and equipment, including:
- Vertical Pumps and Turbines
- Heavy-Duty Gearboxes
- Crane Hooks and Lifting Equipment
- Extruders and Injection Molding Machines
- Large Industrial Presses
